No. 15,752 Claims priority, application Canada June 9, 1959 2 (Ilaims. (Cl. 29-565) This invention relates to closure means for an opening in a structure and more particularly to a liner for such an opening which is readily insertable in the opening even though the opening is preformed.

In its broadest aspects the invention provides, for an opening in a structure, a liner comprising a member defining a closed area and made of flexible material of channel section with the limbs of the channel extending outwardly, said member being prefabricated for the particular size and shape of the opening for which it is intended, and being of such dimensions that the limbs of the channel will overlap the structure around the opening and the base of the channel will be spaced inwardly of the edges of the opening, the flexibility of said material rendering the liner readily insertable in a preformed opening.

Window panes may be secured to the opposite faces of the liner to form a double window pane construction having a heat insulating air space between the panes. The expansion and contraction of the insulating air as a result of varying conditions is allowed for by the flexibility of the liner material and the spacing of the base of the channel inwardly of the edges of the opening.

An embodiment of the invention will now be described, by Way of example, with reference to the accompanying drawings, in which:

FIGURE 1 is a perspective view of a liner according to the invention.

FIGURE 2 is a diagrammatic elevational view of a double window pane construction mounted in a wall, With parts broken away for clarity; and

FIGURE 3 is a sectional detail taken on the line IIIIII through the lower end of the double window pane construction shown in FIGURE 2.

Referring to FIGURE 1 the liner comprises a member 1 defining a closed area 2 and made of flexible material of channel section with the limbs 3 and 4 of the channel extending outwardly, the base of the channel being designated by reference numeral 5. The limbs 3 and 4 extend outwardly preferably about two inches from the base 5 and the liner may be made of a flexible plastic material or other suitable material.

Referring now to FIGURES 2 and 3 it will be seen that the liner 1 is fitted into an opening 6 in a wall 7 so that the limbs a and 4 overlap the wall around the opening. A strip of caulking cement 8 is applied to the outer faces of limbs 3 and 4 and sheets of glass 9 and 10 are pressed against the limbs 3 and 4, respectively, so as to be secured thereto by the cement 8. Mouldings l1 and 12 are secured by screws 13 to the outside and the inside of the wall, respectively, and engage the window panes 9 and lit) to hold same in position and to press the limbs 3 and 4 of the liner 1 tightly against the wall '7.

The space enclosed by the panes 9 and 1t and the liner 1 acts as an insulating air space sealed off from the atmosphere by the cement strip 8 and capable of expansion and contraction in response to variation in the surrounding conditions by virtue of the flexibility of the liner 1 and the spacing of channel base 5 slightly inwards of the edges of opening 6.

It will be manifest that various modifications may be envisaged without departing from the scope of the present invention. For example, where only a single window construction is necessary the liner may be positioned as described above and the cement may be applied to only one or" the limbs for securing a window pane thereto, the other limb simply being stapled to the wall. Moreover, in the case of an ordinary Wooden sash window the wooden sash may be secured to one limb of the liner and the assembly secured to the wall by screws passing through the Wooden sash and the limb into the well.

What I claim as my invention is:

l. A structure having closure means for an opening in said structure, said closure means comprising a liner defining a closed area within said opening and made of flexible material of channel section with the limbs of the channel facing outwardly and overlapping the structure around said opening, the base of the channel being normally spaced inwardly from the edges of said opening, and two sheets of transparent material secured one to each side of said liner to completely seal said closed area.

2. A structure as claimed in claim 1, including mouldings secured to the structure and embracing the edges of said sheets of transparent material.

1. A STRUCTURE HAVING CLOSURE MEANS FOR AN OPENING IN SAID STRUCTURE, SAID CLOSURE MEANS COMPRISING A LINER DEFINING A CLOSED AREA WITHIN SAID OPENING AND MADE OF FLEXIBLE MATERIAL OF CHANNEL SECTION WITH THE LIMBS OF THE CHANNEL FACING OUTWARDLY AND OVERLAPPING THE STRUCTURE AROUND SAID OPENING, THE BASE OF THE CHANNEL BEING NORMALLY SPACED INWARDLY FROM THE EDGES OF SAID OPENING, AND TWO SHEETS OF TRANSPARENT MATERIAL SECURED ONE TO EACH SIDE OF SAID LINER TO COMPLETELY SEAL SAID CLOSED AREA.
